background: misoprostol, a prostaglandin e1 analogue compared to prostaglandin e2, has the advantage of being inexpensive and stable at room temperature, with its proven efficacy and safety. however studies on the effect of ph on the efficacy of misoprostol have yielded conflicting results. thus its use in the induction of labour in patients with premature rupture of membrane requires further i...

The objectives were to estimate (co)variance components and genetic parameters for lactation curve traits in Holstein dairy cows in Iran. The used data were records on Holstein cows collected during January 2003 to December 2012 by the Animal Breeding Center of Iran (Karaj, Iran). In order to describe the lactation curve, an incomplete gamma function was fitted to 691200 test-day records on 962...

During lactation, branched-chain aminotransferase (BCAT) gene expression increases in the mammary gland. To determine the cell type and whether this induction is present only during lactation, female rats were randomly assigned to one of three experimental groups: pregnancy, lactation, or postweaning. Mammary gland BCAT activity during the first days of pregnancy was similar to that of virgin r...

from 10d to 15d (P<.01), indicating onset of lactation. Megalin expression increased about 3-fold from 0d to 5d (P=.01), then decreased 2.8-fold by 10d (P=.01). Gene expression of LDL-R decreased 4.5-fold (P<.06) from 5d to 10d while folic acid receptor mRNA decreased about twofold (P<.05). We conclude that temporal changes in expression of megalin, LDL-R and folic receptor mRNA during colostro...

the purpose of this study is to show the effect of extraamniotic administration of corticosteroids to shorten the times to either active labor and/or delivery. this is a double blind randomized study. 65 patients who were candidates for the termination of pregnancy between the ages of 16-45, with intact membranes and unripe cervix were randomly divided into two groups, a study group (n=34) and ...

The aim of the present study was to compare the occurrence and duration of clinical mastitis in different seasons, stages of lactation period and parities in a Holstein dairy farm in Iran. A retrospective epidemiological survey from April 2005 to March 2008 was conducted on 884 clinical mastitis cases of 7437 lactations. Data of each case including calendar-date of mastitis onset, days in milk ...
